ITPEC FE Morning April 2020 Question 50
ITPEC FE Morning April 2020 — Question 50 of 80
Reverse Engineering — analyzing existing software to recover its specification and structure.
Reverse engineering takes a finished product and works backward to understand its design, architecture, and behavior.
Why not others:
- (a) Re-engineering — reconstructing the entire software after analysis (goes beyond just understanding)
- (c) Refactoring — changing internal structure without altering external behavior
- (d) Auto code generation — creating source code automatically from design information using a tool
Key distinction: Reverse engineering = understand what exists. Re-engineering = rebuild it. Refactoring = clean it up.
